My grandma went in for tests, and they found a mass, which they think is a tumor, in her right lung, What can be done for this? They don't know if it's benign yet, and I am so afraid I am going to lose my grandmother because she doesn't want to go for cancer treatment if it is a tumor, and my dad keeps telling us my mom is crying when we aren't around, and he keeps saying that losing a close relative is the hardest thing, and he makes it out like she is going to die, someone please help, I feel like my heart hit the floor!

It's just your dad's way of dealing with the situation, he is just thinking about the probabilities, something like "She is of old age, the tumor might be malignant and she does not want treatment". but what your dad and mom think or feel has no influence in the outcome, so just understand that they are going through a lot of pain and worry too. You have to wait until the diagnosis is complete and evaluate the options, that's all you can do for now; be realistic, but don't loose hope

Please don't worry, I think everything would be fine. First you need to talk with your grandma to make her believe and confidence that she will be fine. Also I have some good information who self recovered from cancer. If you read, it would be useful for your grandma. Don't worry its free, I would like to truly help. If you want to read it please send your email to me then I will reply with attachment file.
